Model Ashley Graham revealed she was sexually harassed on the job at age 17

The INSIDER Summary:

Model Ashley Graham is on the cover of the July issue of Glamour magazine.

In an interview, she revealed that she was sexually harassed on a photo shoot when she was only 17.

Graham said the incident inspired her to take more control when she's on set.

In a brand-new interview for July's issue of Glamour magazine, model Ashley Graham opened up about an experience she's never before revealed: When she was only 17 years old, an assistant on a photo shoot pulled her into a closet and exposed himself.

Glamour's Lauren Chan asked Graham how she knows her boundaries when she's working on set. Here's how Graham responded:

"There was an incident on set of a campaign job when I was 17 years old — I haven't told this story — and there was a photo assistant who was into me. He was like, 'Hey, come here,' and he led me into a closet. And I was like, 'What?' I thought he was going to show me something. And he pulled me in, and he pulled his penis out. And he was like, 'Grab it.' And I was like, 'No! That's disgusting.' I freaked out. And thank God I was closer to the door, and I just bolted out."

Graham was so shaken that she didn't tell anyone at the time — and in later years, she continued to see the man at other jobs she booked.

But she also told Glamour that the experience taught her the importance of standing up for herself at work.

"I told myself, ever since that incident, that I wasn't going to allow someone at work to manipulate what I wanted to do on set," she said. "So any image that you see out there is one that I wanted to take."
